An electric stapler is operated by a paper bundle pinching step of relatively moving a table part and a driver unit and also pinching a paper bundle; a staple separation step of folding a staple into U-shape by a forming plate and also separating the folded U-shape staple from a staple sheet by moving a driver; a penetration step of penetrating legs of the staple into the paper bundle by further moving the driver; a clinch step of inward folding the legs by a clinch device; and a paper bundle releasing step. A relative movement of the table part and the driver unit, the forming plate, the driver, and the clinch device are powered by a single motor. A driving speed of the motor in the steps excluding the penetration step and the clinch step is slower than the driving speed of the motor in the penetration step and the clinch step.

Electric stapler and operation method of electric stapler

A staple leg cutting mechanism includes a fixed cutter interposed between staple legs penetrated through binding sheets and a pair of movable cutters disposed movable from the outside of the staple legs to the inside thereof, and a clincher mechanism that includes a pair of movable clinchers, respectively disposed on the lower surface side of their associated movable cutters. The staple legs penetrated through the binding sheets are formed in an inwardly curved manner by the movable clinchers and are then guided into and between the movable cutters and fixed cutter. The movable cutters are moved from the outside of the staple legs to the inside thereof to cut the leading end portions of the staple legs, and the staple legs are bent along the binding sheets by the movable clinchers.

Stapler

A slide frame is mounted on a driver unit that can be vertically reversed on a base frame. A guide pin disposed in the slide frame engages with a concave portion of a cam plate portion formed in the base frame. When a fixation releasing handle of the driver unit is operated, a lever pushes the slide frame to slide the slide frame and the guide pin is deviated from the concave portion to rotate the driver unit. In a state where the driver unit is fixed in a regular posture, since the guide pin is pushing a switch lever, the detection switch is kept turned ON and thus an electric stapler is in an operable state. When the driver unit is rotated, the switch lever is released from the press of the guide pin and the detection switch is turned OFF, thereby cutting off the power.

Electric stapler

A stapleris provided with a cutter unitfor cutting a leading end portion of a staple leg projected to a back face side of sheets. A staple cartridgecontaining a number of staples is formed with a chip containing portionfor containing a chip of the staple leg. The chip of the staple leg cut by the cutter unitis guided into the chip containing portionof the staple cartridgeby a chuteformed on the cutter unit. The chip of the staple leg is collected in the staple cartridge

A forming plate and a driver plate are held at a front portion of a path of supplying connected staples in a laminated state. A staple in a C-shape formed at an inside of a strike out path formed between a front end face of a supply path and a back face of the face plate arranged on a front side of the supply path is pressed to supply to inside of the strike out path toward the face plate by a pusher urged by a spring. The staple is struck out by the driver plate. The pusher is made to constitute a first pusher, and a second pusher for pressing a leg portion of the staple to the face plate is aligned to be arranged to a side of a staple strike out port of the first pusher.

Stapler and staple cartridge

A cut chip of a staple leg cut by a cutter unit is discharged to a lower face side of the cutter unit by way of an opening formed at the cutter unit. The cut chip is guided in directions of both sides of the stapler by a pair of chutes arranged on a lower face side of the cutter unit to be continuous to the opening portion. The cut chip guided by the chutes is guided to a containing portion formed at a rear lower portion of the stapler by way of guide case portions formed at both side faces of the stapler.

Stapler with a mechanism for cutting staple legs

A staple cartridge provided with a cartridge main body and a refill contained with connected staples. The refill is interchangeably attached to the cartridge main body. A guide portion for guiding the connected staples at an inside of the refill to a staple strike out portion is provided between a refill mounting portion and the staple strike out portion. Lower portions of the guide portion and the refill mounting portion are respectively arranged with a first actuator operated in accordance with a presence/absence of the connected staples at an inside of the guide portion and a second actuator provided in accordance with a presence/absence of the connected staples at an inside of the refill mounting portion. The first actuator and the second actuator are interlocked.

Staple cartridge

A staple refill which can be stored in a refill storing section in such a manner that the leading one of the sheet-like joined staples wound in roll form is on the upper side and which is adapted to lessen the load on a feeding mechanism for feeding the leading one of the sheet of joined staples in a stapler main body. The staple refill is removably attached to a cartridge installed in a stapler main body. A refill includes a storing section for storing a sheet of joined staples wound in roll form, a discharge port for discharging the sheet of joined staples, and a lead-out passage for leading out the leading part of the sheet of joined staples into the discharge port. The lead-out passage is upwardly bent from the discharge port toward the interior of the storing section, so that the leading part positioned on the upper side of the sheet of joined staples is lead out to the discharge port. The lead-out passage is provided with a retrograde motion preventive member which prevents movement of the sheet of joined staples to the storing section.

Staple refill with backward movement preventing member

A cartridge from which a staple refill cannot be taken out until all sheet-like connected staple is discharged. A cartridge is drawably provided in a stapler body and has a receiving room for receiving a staple refill, an engagement member with which one side of the staple refill is engaged, and a lock member for locking the engagement member. The lock member has a contact portion that comes in contact with a sheet-like connected staple, discharged from a discharge opening of the staple refill, when the staple refill is received in the receiving room. When the contact portion is in contact with the sheet-like connected staple, the lock member locks the engagement member to prevent separation of the staple refill.

Cartridge

The actuator () is swung and tilted in the perpendicular direction to the longitudinal direction of the passage () and biased by a spring so that it can obliquely rise at all times.

Staple detection mechanism of electric stapler

A motor driven stapler in which there are no fears of cutting off and need for loosed part of the lead wires of photo sensor for detection of sheets to be bundled, is provided. The stapler comprises a driving out portion from which a stapler is driven out; a table which forwardly and backwardly reciprocates; and a clincher which is disposed on the table so as to put and hold a pile of sheets to be bundled between itself and the driving out portion when the table forwardly moves and at the same time a stapler is driven out from the driving out portion against the pile of sheets, and to clinch the front end portions of the staple which penetrate through the pile of sheets, wherein a photo sensor is disposed in the other side of table opposite to the driving out portion; and one or more through holes are arranged in the table in order to guide the emitted light beam from a light emission diode of the photo sensor to the pile of sheets and to guide the reflected light beam from a surface of the pile of sheets to a light receiving diode of said photo sensor
